I've tried all kinds of values. For sure I've tried the ones that Postgres says will work at least 6 times. I wonder if this is a bug?

I think you possibly have the meaning/units for shmall and shmmax
reversed. shmall is in pages, shmmax is in bytes. I wouldn't be
surprised if the shmall value you're trying to stuff in there is
overflowing to zero...
